Resources Question

I have decided to try the resources for adding new pages and photos in RW7 (up to date).

I dumped a few photos into the resources and placed them where I wanted within the project. Now, my question is this… If I add a folder and drop these photos in a folder, will the links in RW automatically adjust or will I have to reset the links?

One more question: Can folders be nested and work within the resources? As part of my web page, I tell a brief story of some of the projects I work. I already have 21 projects in RW (with about 14 actually published). What I would like to do is nest them as /projects/project_name/. Would that work?

Thanks, in advance, for your help.
